"... especially Indochina and Algeria. The founding of a Fifth Republic was supported by the French people, while France's colonies were given the choice between more autonomy in a new French Community and immediate independence. The other colonies chose the former but Guinea — under the leadership of Ahmed Sékou Touré whose Democratic Party of Guinea had won 56 of 60 seats in 1957 territorial elections — voted overwhelmingly for independence. The French withdrew quickly, and on October 2, 1958, Guinea proclaimed itself a sovereign and independent republic, with Sékou Touré as president."

And that was the beginning of the modern state called Guinea, today's "History of" country.
